Yes, temperature does affect the solubility of sugar in water. Generally, sugar dissolves more easily in hot water than in cold water because the increased kinetic energy at higher temperatures helps to break down the bonds between sugar molecules.
The mass of both solute and solvent are conserved (sugar water weighs the same as the sugar plus the water), the volume of the solution increases less than the dry volume of the sugar, so the density of the solution is higher than water.
if by reversible you mean can you get it back as regular sugar than yes
well, sugar is more dense than water. Therefore, sugar will sink to the bottom until it's dissolved into a substance. (:
Cold water generally has more dissolved gases than hot water. This is because gases are more soluble in colder temperatures compared to warmer temperatures. When water is heated, its capacity to hold dissolved gases decreases.
hot water has faster moving particales than cold water
Sugar sinks at the same rate in warm or cold water. Sugar dissolves faster in warm water.
I assume that you mean 'dissolves in water'. The answer is yes, very much so. The higher the temperature of the water, the quicker the sugar dissolves. The reason for this is very simple. As the temperature increases, water molecules move more quickly as they have more energy. They are therefore more likely to collide with and 'attack' the sugar crystals, causing sugar molecules to separate from each crystal and disperse throughout the water forming a sugar solution.
Sugar dissolves in water faster than salt because of the structure and bonding of its atoms. The atoms of Sugar are bound very loosely whereas the atoms of salt are tightly bonded as compared to the sugar atoms. That is why sugar dissolves faster than salt.
